Buttocks

When it was about bed time last night, daddy, mummy and I were all prepared to sleep. Di-di was sleeping soundly then. Usually we will have a little chit-chat first before we all fall asleep. So as usual, last night, we chat and chat. Suddenly:

Yin Yue: "Daddy ah, can you help me go down to kitchen, and bring the knife, to cut my buttocks?"
Daddy: "Why you want to cut your buttocks???"
Yin Yue: "Because ITCHY ah!"

HAHAHAHAHAHAHAHAHAH!!!
